So, you probably know how to put an equation into standard form by now., which looks like this:
aX+bY+or-C=0
Now, you'll learn how to put this equation into y=mx+b form.
This was a question on my Accelerated Math. Write the equation in slope and y-intercept form 3x+2y-9=0
a)y=(3/2)x-9/2 b)y=(-3/2)x-9/2 c)y=(-3/2)x+9/2 d)y=(3/2)x+9/2
Step 1
Subtract the 3x from both sides
3x-3x+2y-9=0-3x
2y-9=-3x
Step 2
Add the 9 to both sides
2y-9+9=-3x+9
2y=-3x+9
Step 3
Divide everything by 2
2y/2=(-3/2)x+9/2
y=(-3/2)x+9/2
And you have your answer, which is c. Depending on the kind of question, you'll have to add or subtract accordingly
Here are a few questions to try if you want to practice
